Last week I was browsing other crochet blogs and I came across The City of Crochet at http://cityofcrochet.blogspot.com/
Its author had posted a pattern for a woven potholder or trivet. I had just bought some cotton yarn because it was $1 a skein on the clearance aisle and thought it would be perfect. See my mother doesn't understand how you buy yarn just for the purpose for being able to create things as soon as you find the pattern without running to the store.
Here is my finished project. I accidentally sewed it wrong and didn't follow the weaving correctly (i was too busy watch TV) but it still works and looks good.
